Our objective was to compare the efficacy of different lengths of rubber tube (6 French) on patients with esophageal stent implantation performed using a silk thread. We measured the effects in terms of pain and foreign body sensation felt in the pharynx and esophageal mucosa of the patients. A retrospective analysis was conducted using records of 65 patients who were divided into 3 groups. Group A had 20 cases with the distal end of the tube toward the nasal cavity, Group B had 21 cases with the distal end of the tube reaching the nasopharynx without exceeding the soft palate, and Group C had 24 cases with the distal end of the tube toward the upper end of the stent. Follow-up was performed on 1 day, 2 days, 1 week, 2 weeks, 4 weeks, 6 weeks, and 8 weeks postoperatively. During each period, the pain scores for Groups B and C were lower than those for Group A (p < .05), whereas no difference was observed when Groups B and C were compared. Although no variations were seen between the 3 groups in terms of the proportion of patients with foreign body sensation on the first day (p > .05), Groups A and B had a lower proportion than Group C (p < .05) at those periods. No difference was observed when Groups A and B were compared. In conclusion, the Group B method was successful in alleviating the side effects caused by the silk thread.
